CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 355,979, dated January11, 1887.

Application filed December 26, 1885. Serial No. 186,666. (No model.)

. and it consists in the improved construction hereinafter described andexplained.

In the accompanying drawings, forming a part of this specification,Figure l is a per spective view of a car-coupling embodying myimprovements, a portion ofa link being in a coupled position within thedraw-head. Fig. 2 is a like view, a portion of the draw-head beingremoved to show the interior construction of the same. Fig. 3 is aperspective view of an ordinary link, and Fig. 4 is a detail view of thespring used in the draw-head.

A designates the draw-head, which may be of any approved form, and whichis provided at its upper face, at each side, with a pair of bearings, c0, in which rest thejournals of the bar B, extending transversely acrossthe draw head. One of the journals is extended for the attachment of anoperating-handle, b.

The top portion of the draw-head is provided with an elongated slot, E,and is intersected centrally with the bar B. In line with said Slot is acoupling-pin, C. This couplingpin is preferably of the form shown inFig. 2, and consists of a cylindrical portion, 0, forming the pinproper, the upper end thereof be ing reduced or flattened to the formofa shank, d, as shown, which shank leaving the shoulder passes througha corresponding opening therefor in the bar B,the object ofsaid openingbeing. to permit the ready insertion of the couplingpin into thedraw-l1ead and its withdrawal therefrom.

The lower portion of the draw-head is recessed, as indicated at e, whichrecess deepens toward the front of the draw-head, as shown in Fig. 2, sothat the lower front edge of the draw-head presents on its lower insidea stopshoulder, upon which the pin 0 contacts. The lower end of the pinis curved to correspond with the adjacent face of the depression.

D, Fig. 4, refers to a spring, which is of the shape represented, andconsists of two parallel tongues, ff, which are perforated. for theattachment to the draw'head top, as shown in Fig. 2, the free portion ofsaid. spring being bent downward and then inward to present aspring-bearing against the rear vertical wall of the coupling-chamber.

The operation of the device is as follows: The link enters the mouth ofthe draw-head and, contacting with the pin, swings the same upon itspivots until the end bar of the link clears the end of the pin, when thelatter falls by gravity to its former position, with its lower portionin the eye of the link. The link may be readily disengaged from the pin0 by means of the handle I). The spring D not only serves as a buffer toreceive the impact of .the link, but yields to permit the end portion ofthe latter to pass beneath the same to maintain said link in properhorizontal position.

What I claim,and desire to secure by Letters Patent, is-

1. In a car-coupler, the combination, with a draw-head having a slottedtop and a recessed bottom, of a transverse slotted bar journaled inbearings, one end being extended for the attachment ofa handle, and theheadless coupling-pin having the reduced or flattened portion to permitof its ready insertion and withdrawal from the transverse bar, substan-'tially as and for the purpose set forth.

2. In a car-coupler, the combination, with a draw-head, A, having aslotted top, E, and recessed bottom e, of a transverse slotted bar, B,journaled in bearings c c and having one end extended for the attachmentof a handle, the headless coupling-pin 0, having the reduced orflattened portion (1, to permit of its ready insertion and withdrawalfrom the transverse bar B, and the internal spring D,provided withperforated tongues f f, for its attachment to the draw-head, all asherein shown, and for the purpose set forth.
